To n/ZZ whom it may con/cern,.-

Be it known that I, CAsIMIR voN PHILP, a citizen of the United States,and a resident of Bethlehem, Northampton county, State of Pennsylvania,have invented certain new and usefulA Improvements in Fluid PressureMetal-Working Machines, of which the following is a specification.

This invention comprises various improvements in fluid-pressuremetal-working machines such as are employed for langing or rivetingmetal plates and for other purposes.

The invention will be described in detail in connection with theaccompanying drawings, in which- Figure 1 is a' vertical section onthe-line a b of Fig. 2 of an apparatus embodying my invention. Fig. 2 isa top plan view of the apparatus, the upper pla-ten being broken away,so that the lower platen may be seen. Fig. 3 is a section on the line cd of Fig. 1. Fig. 4 is a vertical section of the working cylindermounted on the up er platen and Fig. 5 is a top plan view of t e Workincylinder with the head removed, showing tIie plunger and plunger-guide.

Referring to the accompanyin drawings, the apparatus comprises a suitale foundation on which is mounted a bed-plate A, supporting uprights B.Upon the uprifrhts are slidably mounted .an upper platen O and a lowerplaten D. Fixed to the bed-plate A is a hydraulic device E for raisingthe lower platen D. The bed-plate A also supports hydraulicjackcylinders F, the plungers of which may extend above the lower platen-for supporting the work. Adjustably secured within the upper platen Cis a hydraulic cylinder G, the plunger ofwhich carries a tool or isotherwise suitably arranged and constructed to work upon the metal.

The upper platen O may be secured in any desired position upon theuprights B by means of lock-nuts 1, engaging with screwthreads upon theuprights. The upper platen has a slot 2, wit-hin which the cylinder G isslidably mounted. The cylinder G has lugs 3, which rest upon'the top ofthe platen and also lugs 4, which extend into grooves 5, cut in. thesides of the slot 2 and between the upper and lower faces of the platenC. By this construction ease of movement and security in position of thecylinder G is secured.

The interior ofthe outer cylinder 6 is of the usual cylindrical form,within which its a hollow plunger 7. At the top of the plunger issecured a cylinder-rin 10 by a ring 11, fixed to the end of the p un erby bolts 12. Farther down the plunger is ormed a lug 13, by means ofwhich a second cylinder-ring 14 is secured to the plunger. At the bottomof the cylinder a similar c linder-ring v15 is secured by a ring 16 andh der. A short distance from the bottom of the cylinder a lug 18 isformed upon its interior, which lug operates to secure another cylinderring 19. A guide 9, iixed to the head of the cylinder, has longitudinalgrooves 20, into which extend lugs 21, fixed to the interiorof theplunger. In order that the lugs may fit the grooves accurately, liners22, machined to fit the grooves, may be secured to the lugs. Thecoperation of the lu s and grooves prevents turning of the p ungerwithin the cylinder, and thereforeprevents twisting of a tool which maybe carried by the cylinder with relation to the work. The space withinthe plunger may be connected with a source of fluid-pressure, as a headof water, by means of a pipe-connected with an opening 23. y sections 24and 25, whic are jointed to each other, Vso that they may turn. Theother ends of thesections are jointed to the cylinder 6 and to astationary-pipe-head 26, secured to an upright B or Vother stationaryportion of the apparatus. the pipe-sections 24 and 25 are of suHicientcombined length to permit the cylinder G to move to the end of itstravel, while the oints between the stationary pipe, the cylinder, andbetween the sections are such as to permit the flexure of thepipe-sections, so that the cylinder G may be moved along the slot 2. Theopening 23 is also connected to an outlet pipe which may be controlledby a valve in any suitable manner.

In the outer cylinder 6 is a hole 28, which connects with a source ofpressure and also with an outlet in a manner similar to that noted inconnection with the opening 23. The hole 28 opens into the outercylinder between the cvlmder-rings 14 and 19. If now the controllingdevices be so turned that the space between the cylinder-rings 14 and 19and between the plunger and the outercyl- As will be noted,

olts 17 to the cylinlOO ' is connected with the source of pressure. The

' being connected to .the cylinder and the other' plungerwill be thenforced 4upwardly into-.po-

sition for lanother stroke.

As 'before stated, vthe cylinder y.Gr .ma be moved along fthe slot 2,and it .may beehe d in any desired position by means ofclampingscrews29,.carried bythe lugs 3 and engaging! with the top of the upper platen.The cylinder;` G may -be moved along theslot 2 -by a .relatigvelymovable screw 3U' and sleeve 31,

whicharein engagement with each other,.one

to the platen'. The .relative :movementmay -be effected by means of .asquared end 32 upon the screw, to which a wrench `may be applied.'

The lower platen D is fixedto a plunger 33,v the 4hydraulic device E,which vis .supported vin 4the bed-plate itted within. thecylinder of A.The space vwithin the cylinder .between it andthe plunger eis connectedin any suitable. manner with ,a source of 4pressure and also :hassuitable Vmeans of exhaust. When theexhaustis closed andthepressureconnection opened, ythe-plunger 33 will be forced upthe .platen with it,the d lswardly, carrying tance .to whichthe. laten is moved -fbeingregulated by controlllng they pressure connections. If vit -be desiredto lower the platen, the -pressure connections are closed', .while theexhaust'is opened, when the platen and -plunger lwill -fall ,by'theirown welght. U onthe bed-plate ,are fmounted @wooden bu ers 34, againstwhich the platen strikes on its return movement. The use'of wood in thisconnection .has-'beenffound peculiarlyadvantageous,

as it secures the stoppage of theplaten without l undue shock.

The jack-cylinders F com rise-an outer cylinder in which is mounte meansfor=admitting.pressur'e toand .releasing ressure :from :the space withinthe cylinder eneath .the .plunger :infany suitable manner. Each'gjackgis slidably mounted ulplen .a .radially-extending track 35, along w 'chit may be moved by means of avrelatively movable nut 36 and screw 37,which engage with each other and are connected one-tothe jack-.cylinderand the other to the bed-plate, sothat-they may lhave relative movement,Aand .thereby cause the cylinderto move alongthe track. :In the resentinstance the nut is shownasx'ed to t e 1jack-cylinder, while the screwAis1-om- -tably secured to the 1bed-plate and extends a plunger withparallel to the track. 4Slots 38611 the lower platen permit the plungersof the jacks to extend .above Athe said platen, :and fas z'dhe fslots-are parallel to the tracksmovement of the jacks along the tracks ispermitted. The jacks F are obviously proachtoward the-center of theplaten, and therefore any work which Ais supported -upon the plungers of.the jacks is necessarily unsupported in the center.. It may, however,ybe desirable under some circumstances that the center of the work besupported. To accomplish this, a second plunger'39 is mounted ywithinthe iplunger3 of thecylinder E.

The various plungers and the faces of the platens mayhave T-shaped slots42 for securing the work.

The dotted lines in Fig. 1 show the machine arranged to operate as aHanging-press. The plate 43 to be' flanged rests upon a die 44,supported by the projected plungers `of the jacks, the Hanging beingperformed by the head 45, secured to the plunger 7, which is projectedagainst the' plate in a manner` before described.
